TEST PROCEDURES FOR TEST KIT FLOW METERS
THE INFORMATION IN THIS MANUAL IS FOR GENERAL APPLICATION ONLY. ANY INFORMATION FURNISHED BY THE
MANUFACTURER OF THE MACHINE’S HYDRAULIC COMPONENTS SHOULD BE FOLLOWED. SPECIFIC SYSTEMS MAY
REQUIRE SPECIFIC TEST PROCEDURES.
General Information
The VA High Pressure Test Kits are designed to measure flow and pressure . Power measurements are derived from the product
of flow and pressure . When using a test kit, power can be calculated using the following formulas:
HP GPM x PSI
=
1714
HP LPM x bar
=
447 4
.
kW LPM x bar
=
600
Standard Test Conditions
1 . Install the test kit as described in one of the following test procedures:
a .
b .
c .
"Pump Test Using Tee Test Configuration" on page 11
d .
"Relief Valve in Separate Housing" on page 11
e .
2 . Open the loading valve fully by turning the handle counterclockwise .
3 . Start the pump and adjust it to the rated speed .
4 . Open the test kit loading valve fully and proceed with the required test procedure .
5 . The test kit will indicate flow and pressure .
Pump Test
A tee must be installed between the pump discharge port and the return line to the tank . Be sure the fluid path is only
through the pump, the hydraulic test unit and back to the tank . See

Figure 6: Pump test
1 . Plug the line to the control valve .
2 . Open the test it loading valve fully to read maximum pump flow at zero pressure .
3 . Close the loading valve to increase pressure from zero pressure to rated or maximum pump pressure to determine
pump condition .
4 . The pump flow at rated pressure can now be checked against the pump manufacturer’s specifications . A decrease in flow
from zero pressure to maximum pressure indicates the pump condition . A pump that delivers a constant low flow at zero
pressure and at maximum pressure suggests suction problems .
